CMS03 2006-11-13 2 marking abbreviation code part no. s3 CMS03 standard soldering pad handling precaution schottky barrier diodes have reverse current characteristics compared to other diodes. there is a possibility sbd may cause ther mal runaway when it is used under high temperature or high voltage. please take forward and reverse loss into consideration during design. the absolute maximum ratings denote the absolute maximu m ratings, which are rated values and must not be exceeded during operation, even for an instant. the following are the genera l derating methods that we recommend when you design a circuit with a device. v rrm : use this rating with reference to the above. v rrm has a temperature coefficient of 0.1%/c. take this temperature coefficient into account designing a device at low temperature. i f(av) : we recommend that the worst case current be no greater than 80% of the absolute maximum rating of i f(av) and t j be below 120c. when using this device, take the margin into consideration by using an allowable tamax-i f(av) curve. i fsm : this rating specifies the non-repetitive peak curren t. this is only applied for an abnormal operation, which seldom occurs during the lifespan of the device. t j : derate this rating when using a device in order to ensure high reliability. we recommend that the device be used at a t j of below 120c. thermal resistance between junction and ambient fluctuat es depending on the device?s mounting condition. when using a device, design a circuit board and a soldering land size to match the appropriate thermal resistance value. please refer to the rectifiers databook for further information. 3.0 1.4 2.1 unit: mm 1.4
